Mary’s new in town. She’s worried about starting classes at her new school. That’s why her mom calls the Helper Hounds―and why Sparkplug, the wildly handsome, wickedly smart, card-carrying, world-famous Helper Hound is on the scene. Sparky knows a thing or two about moving. He moved four times as a puppy, and learned to make new friends along the way. Sparky knows he can teach Mary all his best tricks and help her meet new friends, too. At least Sparky thought he could until he met Custard, Mary’s persnickety cat. Will Sparky’s best tricks be enough to win over Custard and show Mary making friends is nothing to fear?
